Holotype ♀, China, Hunan, Yongzhou, Dupangling National Nature Reserve (25.46°N, 111.37°E; elev. 380 m), from the root of Poaceae grasses (Fig. 15), 4.IX.2020, coll. Xia Wang. Paratype. 1♂, same data as holotype.</p> <p> Etymology. This species name is composed of the Latin word, “ <i>elongatus</i> ”, based on its elongated preoclular projection of head.</p> <p> Comments. This new species can be recognized as the genus <i>Ophthalmothrips</i> by the elongated preocular projection of the head, which is about 1.4 times as long as its wide. Similarly, this character is also present to <i>O. faurei</i> and <i>O. longiceps</i>. But the new species differs by having postocular setae small (not reaching at posterior margin of eyes), interocellar setae, pronotal epimal setae well-developed and pelta triangular with slightly rounded laterally. In <i>O</i>. <i>faurei</i>, the original description showed that it had postocular setae well-developed (Ananthakrishnan, 1964); Ananthakrishnan (1973) redescribed both sexes of <i>O</i>. <i>faurei</i> in detail, of which its postocular setae were also developed, interocellar setae absent, and one pair of median dorsal setae of head well-developed (but we think that these setae were probably located ventrally.); Haga (1975) studied Ananthakrishnan’s specimens of <i>O</i>. <i>faurei</i>, and showed that the pronotal epimeral setae are small and the interocellar setae developed. The genus <i>Ophthalmothrips</i> was reviewed worldwide by Minoura & Mound (2019) as the latest research. They recorded only one female represented as <i>O</i>. <i>faurei</i> from Guilin City in China, but the author helped to re-check this specimen, and found its head was too dark to see any characters. And the specimens from Japan identified as <i>O</i>. <i>faurei</i> together with Chinese specimen showed developed postocular setae. Thus, the only female specimen identified as <i>faurei</i> need to further study in the future. In <i>O. longiceps</i>, it is distinguished from <i>O</i>. <i>elongatus</i> Li & Dang, <b>sp. nov.</b> by the shorter preocular projection (wider than long), the well-developed postocular setae, and the pelta sharply pointed laterally.</p> <p> Figures 16–25. <i>Ophthalmothrips formosanus</i> (16–17, 21–22, 24), <i>O. miscanthicola</i> (18, 20, 23) and <i>O. longiceps</i> (19, 25). 16.

Although the efficacy is under exploration, fire needling therapy is considered an effective alternative for KOA. This trial aims to investigate the effectiveness of different frequencies of fire needling therapy in attenuating pain and promoting function in KOA patients.Methods: This is a study protocol for a pilot, three-arm, single-center, randomized controlled trial. A total of 90 participants with KOA will be recruited and randomly assigned to the high-frequency fire needling group (3 sessions per week, for 6 weeks), the low-frequency fire needling group (1 session per week, for 6 weeks) or the positive control group (Diclofenac Diethylamine Emulgel, 3 times per day, for 6 weeks) in a 1:1:1 ratio. Participants will accomplish the trial at Week 14 after a follow-up evaluation. The response rate will be set as the primary outcome that the proportion of participants obtaining a minimal clinically important difference, which is identified as ≥ 2 units on the numerical rating scale (NRS) and ≥ 6 units on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function score at Week 6 compared with Week 0. Secondary outcomes are NRS, WOMAC, Brief Pain Inventory, Short-Form Health Survey-12, Timed Up and Go Test, and pain threshold.Discussion: This is the first standardized protocol comparing fire needling therapy and positive control drugs. This trial may provide reliable evidence for the effectiveness of fire needling therapy and dose–effect property of it in KOA. Trial registration: The trial has been registered on Chinese Clinical Trial Registry (Registered number: ChiCTR2100043041), registered on 4 February 2021.Keywords: knee osteoarthritis, fire needling therapy, different frequencies, dose–effect propert
Fano resonance from a one-dimensional topological photonic crystal
No full textAn ultra-compact one-dimensional topological photonic crystal (1D-TPC) is designed in a single mode silicon bus-waveguide to generate the Fano resonance lineshape. The Fano resonance comes from the interference between the discrete topological boundary state of the 1D-TPC and the continuum high-order leaky mode of the bus-waveguide. Standalone asymmetric Fano resonance lineshapes are obtained experimentally in the waveguide transmission spectrum with a maximum extinction ratio of 33 dB and a slope ratio of 10 dB/nm over a broadband flat background
